The Acer IPIMB-AR Rev 1.02A motherboard is an OEM component primarily used in Gateway DX4870, Acer Aspire M3985, and Predator G3620 desktop systems. 

Because it is an OEM part, Acer does not provide a standalone "motherboard manual". To find official documentation, you must search for the full system manual of the computer model it came in (e.g., Gateway DX4870) on the Acer Support Website.  Quick Technical Specifications

Where to Find the Acer IPIMB-AR Rev 1.02A Manual Link

Acer does not always host motherboard manuals separately on their consumer support site; they often bundle them inside the user guide for the specific desktop model (e.g., Aspire M3970).

However, the IPIMB-AR is an OEM board manufactured by Pegatron. Because of this, the most accurate schematic and manual often circulate on technician repair forums and parts warehouses.

To find the manual link:

1. Acer Support Site (Official): Visit support.acer.com and search for the full model name of your computer (e.g., "Aspire M3970"). Look for the "User Manual" or "Quick Start Guide." The motherboard layout is usually found in the "System Tour" or "Inside the Computer" section.

2. Pegatron IPIMB-AR Datasheet: Many hardware database sites (like stason.org or manualslib) host the technical breakdown under the manufacturer name "Pegatron." Search specifically for "Pegatron IPIMB-AR manual pdf."

3. Direct Download Link: If you are a technician looking specifically for the schematic, the board is often cross-referenced with the Aspire M3970 service guide. You can find the official Acer service manual hosted on various driver databases.

   • Common File Name: Acer Aspire M3970 Service Manual.zip (This contains the IPIMB-AR board schematic).

2. What is the Acer IPIMBAR Rev: 102A?

Before you click that manual link, let’s decode the board.

• Manufacturer: Acer (OEM – Foxconn/ECS manufactured)
• Model Code: IPIMBAR (Also seen as "IPIMB-AR")
• Revision: 102A (Usually the second production batch; rev 101A was initial)
• Form Factor: Micro-ATX (9.6 x 9.6 inches) but with non-standard front panel headers.
• Chipset: Intel H81 Express (LGA 1150 socket)
• CPU Support: Intel 4th generation Haswell & Haswell Refresh (Core i3, i5, i7, Pentium, Celeron)
• RAM Support: 2x DDR3 DIMM slots (Max 16GB – 1600MHz, 1.5V only)
• Expansion Slots:
  • 1x PCIe x16 (v2.0)
  • 1x PCIe x1
  • 1x PCI legacy slot (32-bit)
• Storage: 2x SATA 3.0 (6Gb/s), 1x SATA 2.0 (3Gb/s)

Technical Specifications

If you are looking to upgrade components, knowing the hardware limitations of the Rev 1.02A is crucial.

• Form Factor: Micro-ATX (24.4 cm x 24.4 cm). This allows it to fit in most standard PC cases, though Acer cases often use proprietary front panel connectors.
• CPU Socket: LGA 1155. This socket supports Intel Core i3, i5, and i7 processors from the 2nd (Sandy Bridge) and 3rd (Ivy Bridge) generations.
  • Note: If you upgrade to an Ivy Bridge CPU (e.g., i5-3470), ensure your BIOS is updated, or the system may not post.
• Chipset: Intel H61 Express Chipset.
• Memory (RAM):
  • Type: DDR3 SDRAM.
  • Slots: 2 x DIMM slots.
  • Max Capacity: Typically 8GB or 16GB depending on the specific BIOS revision installed.
  • Speed: Supports 1066MHz and 1333MHz (1600MHz may run at lower speeds depending on the CPU).
• Expansion Slots:
  • 1 x PCI Express x16 (Gen 2.0) – For dedicated graphics cards.
  • 1 x PCI Express x1.
  • 2 x PCI legacy slots.
• Storage: 4 x SATA II (3Gb/s) connectors.
• Video: Onboard graphics via the CPU (VGA port included on the rear I/O).

3. Available Documentation Links

Due to the proprietary nature of OEM motherboards, the "manual" is often distributed as a schematic diagram or integrated into the PC's Service Guide rather than a standalone consumer user manual.

A. Schematic Diagram (Most Detailed Resource) For technicians requiring pinouts, voltage regulators, or circuit paths:

• Resource: Pegatron IPIMB-AR Schematic (PDF)
• Source Location: Typically hosted on electronics repair archives such as Elektrotanya, Vinafix, or Bios-Chips.com.
• Search Query: "Pegatron IPIMB-AR schematic pdf"
  • Note: Users may need to wait for a "Get Manual" timer to expire on free archive sites like Elektrotanya.

B. Service Guide (User Manual Equivalent) For users looking for jumper settings, port locations, or upgrade limits:

• Resource: Acer Aspire XC-603 Service Guide
• Reasoning: The IPIMB-AR motherboard is the primary mainboard for the Acer Aspire XC-603.
• Link: Acer Support - Service Guides
  • Instruction: Navigate to Support > Service & Repair > Enter Serial Number or SNID (if available), or search "Aspire XC-603 Service Guide" via a search engine.
